Application 111611 January 12, 1925. Serial No. 2.007.

My present invention has reference to a tool for pulling terminals fromthe poles of store e batteries and incidentally for pull-- ing bus ings,timing gears and all other kinds of machinery from their bearings,-andhas for its object the provision of novel means for adjusting the toothcarryin arms of the device with respect toeach ot er to effectively griptherebetween the battery terminal or other article to' be pulled, andwherein the pulling action is effected by the contacting engagement of alongitudinally wherein there is screwed through the block an elementdesigned to contact with a rigid support, such for instance as the poleof a battery on which the terminal to be pulled is arranged, and whereinthe rotation of the threaded element will draw on the arms to effect thepulling operation.

The invention further consists in other novel features of construction,combination and operative association of parts such as is disclosed bythe drawings which accompany and which form part of this applica=- tion.

In the drawings Figure 1 is a side elevation of the ment. 1

Figure 2 is an edge view thereof. Figure 3 is a sectional view on theline 33 of Figure 1.

, Figure 4 is a side elevation with parts in section, illustrating thejaws on the arms engaging a bushing to be pulled.

Figure 5 is a side elevation showing the manner in which a sleeve is tobe pulled.

Figure 6 is a fragmentary perspective view of the aw end of one ofthearms illustrated in Figure 5.

Figure 7 is a fragmentar elevation illustratin the manner in whic thetool is em ploye for pulling a terminal from a battery pole.

improve- Figure 8 is a similar view showing the] manner in which thetool grips a corroded and frosted battery terminal.

As disclosed by the drawings I employ a pair of opposed arms 1 and 2respectively.

Preferably these arms are made up of two strips of metal, and each ofthe arms has its inner edge, adjacent to one of its ends, formed withone or more saw teeth which provide what maybe termed jaws 3. The

plates constituting the arms have their ends, I

opposite that provided with the jaws, bent outwardly and angularly toprovide forks 4. The forked ends of the respective arms are arranged inlapping relation and are secured together by pivot means 5. also entercentral openings in a cross sectionally rounded block 6 which providesthe head of the tool.

The blockl5 has a central threaded portion therethrough, arrangedtransversely with respect to its pivotal connection with the arms, andthreaded through this opening there is a screw 7 having its outer endformed with a These pivots j head 8, the said head being provided withoppositely extending arms 9 whereby the screw may be threaded throughthe block in either direction.

a The screw has on its opposite end ahead 10, and this head is designedto rest on a support, such as a conical element 11 on which a bushing 12is wedged.

The arm 1 has its outer edge formed with a notch 13, and this notch iscovered by a plate 14 secured on the said arm.

Pivotally secured, as at 15, to th arm 2 there are the arms of a yoke16. The yoke straddles the arms 1, 2, and the outer or connectingelement of the yoke has a threaded opening therethrough. Screwed throughthis opening there is a threaded shank 17. The shankhas an outer headedportion 18 and its inner portion is reduced, as at 19,'to

pass throughan opening in the plate 14. The reduced portion 19terminates in a head 20 which is received in the notch 13 of the arm 1.

It will be apparent that by screwing the headed element 17 in onedirection, the arms 1 and 2 will be brought toward each other so thatone of the toothed jaws 3 thereon will rip the lower edge of the bushing12 and firmly sustain the tool on the bushing. The tool is furthersustained by the contacting engagement of the swiveled head 10 with theelement 11. By turning the screw in one direction, the armsrl and2 fwillbe drawn toward the headed end of the said screw and thereby easilyextracting the bushing 12. 1

The construction illustrated in Figures 5 and 6 is similar to thatpreviously described," except that the arms 1 and 2' havetheir outerends formed with lateral extensionsproviding jaws 3-. These jaws may beeither inwardly or outwardl When outwardly directed the aws .en ge thelower edge of a sleeve or the like w ich is, wed ed in an openingtherefor, The

5 end of the head of the screw in port 21. The sleeve is withdrawn bythe turning of the swivele this instance, rests on a sup screw. I

,So far I have described my improvement as a ulling device for bush ngs,sleeves or thelli e, but it is to be understood that the improvement isessentially designed for pulling the lead terminals from the posts ofstorage batteries.

These terminals are susceptible .to disintegration by the battery acid,so that the outer surfaces therof are frequently rendered uneven, andthe said terminals become what is termed frosted on the oles or posts.There is no' manner in which terminals, but with m cons'tructionand asclearly illustrated'in igures 7 and 8 the toothed 'aws on thearms of theimprovement wi bite into the sides of the terminals 20, regardless ofthe outerconfi' ration thereof, that is, regardless of the ape a toolcan be inserted beneath the ofthe terminal "which has beenfpartly eatenby the battery acid. .This -biting e agement insures the easywithdrawalo the terminals when the operating handle of the improvement is rotatedand the swiveled Ahead rests on the outer end of the battery pole orpost. This important function of the improvementv will be appreciated bythose. skilled'in the art to which my invendirected.

tion relates, and while I have. herein set forth a simple andsatisfa'ctoj embodiment of my invention,.I desire it to. understood endsof the arms, pivots connecting the forks and securing the block,therebetween, a. headed 'screw threaded through the block, a head onthey outer end of the screw, a yoke surrounding the arms and pivoted toone,

of said arms, and a screw member threaded through the yoke and swivellyengaging Qwith the free arm.

t In. testimony whereof I aflix my signa-- WILLIAM a. LGILLENTINE.
